| 摘 要： | 通过分析沥青的老化机理,分析了影响基质沥青和改性沥青抗老化性能的因素,总结了目前研究沥青老化的方法以及评价沥青抗老化性能的方法。薄膜烘箱（TFOT）、旋转薄膜烘箱（RTFOT）以及压力老化容器试验（PAV）常用来模拟沥青的老化,并用沥青老化前后的宏观和微观结构的变化评价沥青的抗老化性能。

| Abstract: | Based on summarizing and analyzing the relative literatures,this article introduced the ageing mechanism and the influencing factors of base asphalt and modified asphalt.The methods used to research and evaluate the asphalt ageing were summarized.TFOT,RTFOT and PAV were widely used to simulate the ageing process,the changes of macro and micro properties before and after were served as the evaluation method of asphalt anti-aging performance. |
